3790 additional maps on SD card

Hi
As I have a 3790 with only 1.73GB of memory, I have put the full Euro 2014.20 map & corresponding Jcv file (D3048120A0 ) on the SD card

My intention was to have the "Voice Command " available on the unit for the UK ( apparently does not work with UK & ire only map )
Both maps show under map info ,but when I untick the UK & ire map and then check the voice command I still receive "this feature is not available for England " , back to the map info and the UK map is shown as ticked ,it appears to re-enable itself so I think that is what is still stopping the voice command problem ??

Also the Jcv file is on the SD card ....Garmin/Jcv but not showing photoview ?

Why don't you rename UK & ire to something like UK_&_ire.img1 so that 3790 cannot read it (since you have the full Euro 2014.20 map).
Then you can read this post for the correct placement of the files (especially ASR files).[Only registered and activated users can see links. ]

This info you've heard is wrong: 'I thought that if I removed the gmapprom.img the nuvi wouldn't boot'. Not so, the map img file naming in not important in the boot process itself and the unit will then read it if the path is correct and the naming convention is correct, 'anyname'.img in Map folder on unit or card, gmapprom.img or gmapsupp.img etc in unit .System folder. The important thing is that the detail map is present and readable.

What you may have heard is that occasionally a unit will report 'no detail maps present' after booting even though there is a detail map on the media card correctly but none on the unit. It can be fixed by putting the smallest detail map you can find on the unit [I use Raratonga if i get that rare problem] and all others on the card. I have a 260W which can't fit a World basemap and all of AU NZ and will only acknowledge it on the SD if some tiny detail map is on the unit.

You problem is almost certainly one of conflict between the maps for some reason. Either entirely remove the UK/IR map or rename it as x-trail suggested then use the full EUU, or put only rest of EU less UK/IR from MapInstall, on the microSD. Do a hard reset/clear NV if still having problems, its the best first aid for any stroppy unit.

I guess you've done a typo with the name of the JCV file in the initial post [D3048120A0]. Correct is D3048120A. You could try moving that back to the JCV folder in .System although your reported path is correct for the microSD. Reset might help that too. Also try another card, garmins are flaky with some 'no-brand' cards.

EDIT: Just noticed this when i merged your 2 posts:

Try renaming that to 'gmapsupp.img' first if it's in the card's Garmin folder.

Hi ,
I have dumped the UK & ire img, renamed the Full EUR on the SD to gmapsupp.img , Now I have only the full euro map under map info & it stays selected, so thats fine now .

Still no voice command or Jcv PR ....I have a few different versions ASR files but i dont really know which map they waork but the limits I have are with the SD card only being a 4GB , because the full ASR is 848 Mb, suppose I'll have to try a larger capacity SD card ...

as for the jcv pr ............the D3048120A is the one I have installed so I'm confused about that not working ......

hi
tried ASR1 from
Garmin City Navigator Europe NT(Unicode) 2014.20 , now it tells me voice command not available for british english ??
and this is my path for the JCV file....sd\Garmin\JCV\D3048120A.JCV

Check if you have en_GB.SRD in /.System/ASR (for voice command to work)
Make sure that voice is set to British English Emily and that text is british english and keyboard is british english.
Hard Reset Nuvi and set to United Kingdom.
If you use Express to Download English it should get all the files (Device Optional Updates Language Files English)

Check inventory to see if your JCV file is listed. (File must be listed in Inventory) if not listed
Recheck your path to the JCV file make sure it is \Garmin\JCV\D3048120A.JCV and not \Garmin\JVC\D3048120A.JCV (common mistake)
Maybe your JCV file is corrupt. Make new download.
